About this tag
CVE-2024-49888 is a Linux kernel vulnerability in the BPF (Berkeley Packet Filter) implementation that affects x86_64 systems. The bug involves signed division operations where specific minimum-integer operands can trigger a kernel OOPS, leading to a system crash. This issue is classified as an availability impact. The upstream Linux kernel has released a fix that prevents the overflow condition in signed divide (sdiv) and signed modulo (smod) operations. Discussions on WindowsForum.com cover the technical details of the vulnerability, its exploitation potential, and the patch that resolves it. While the tag is primarily Linux-focused, it may be of interest to Windows users running virtual machines or WSL that rely on the Linux kernel.

    CVE-2024-49888: Linux BPF signed division bug triggers kernel OOPS on x86_64

    A carefully crafted signed-division bug in the Linux kernel’s BPF implementation — tracked as CVE-2024-49888 — can cause a kernel crash (an OOPS) on x86_64 systems when a BPF program triggers specific signed divide or modulo operations with minimum-integer operands, and the upstream fix now...
